An amputation through the wrist joint, referred to as disarticulation, involves the surgical removal of the hand and wrist at the level of the wrist joint. This procedure is indicated when there is a need to remove diseased, infected, or nonviable tissue that poses a risk to the patient’s health. The surgery aims to create a healthy stump that can accommodate a prosthesis, thereby enhancing the patient's functional capabilities. During the procedure, various anatomical structures are carefully managed, including the division of finger flexor and extensor tendons, as well as the identification and sectioning of the median and ulnar nerves. The radial and ulnar arteries are also ligated to control bleeding. The surgical technique ensures that the triangular fibrocartilage is preserved, which is crucial for the integrity of the wrist joint. The final steps involve the careful configuration of skin and soft tissue flaps to cover the newly formed stump, ensuring that it is suitable for prosthetic fitting and functional use.
